If it has a higher COG than a stock JK it will probably roll at less of an angle than a stock JK would roll.

 

Are you talking about off road? Just overall height and being streetable? [since you mentioned your height].

Pitch? Roll?

The number is extremely varying. Tire pressure, speed/momentum, Center of Gravity, spring rates, tire height, track width, wheelbase, there isn't going to be a reliable value that someone can give you. If it's your first rig, it's probably much higher than you feel it is, but there isn't a very good way to answer this.

 

Apologies, I should have clarified. Yes, this is related to off-road only. No crazy fast corner taking for me on-road.

I'm curious how far I can get my Jeep up on rocks, gravel, etc. while crawling before I have to be concerned about that sinking feeling that nobody wants.

I've had it tilted far enough over that I was sliding sideways in my seat (which was awesome), but I don't know if I simply got lucky or if I still had more room to go.

Just looking for an approximate angle as a starting place. I know real-world will provide other challenges as I get to it.

 

For what it's worth, at the official "Camp Jeep" they run people through an artificial obstacle course and the sidehill part is 30 degrees.

 

Awesome. That sounds like a safe starting place. Seems like that could possibly be towards the end of a "green zone" so-to-speak.

Now... to figure out where that yellow-zone is.

 

Heheh I actually at one point had my 2dr with 4 inch lift and 35's so far sidehilling that my mirror touched a rock on the ground. Don't ask me how I did it because if I tried for the rest of my life it would roll before I ever did it again. Best thing to do and the way most of us learn is just wheel as often as you can and the more experience you get the more youll know your rig and push your limits. I will say this though...that jeep can go alot farther than you would think it could and alot farther than it feels like it should be able to. Enjoy it bud.

 

Rules of thumb from a Land Rover University document I read once: At 20 degrees you'll start getting uncomfortable. At 30 degrees your passengers will want out. At 40 degrees you'll probably be in danger of a roll.

A couple things you can get to help you get oriented, Quadratech and 4 Wheel Hardware (4WP) sell inexpensive tilt gauges you can put on the dash. They usually have a "red zone" that starts at 30 degrees. Apple apparently has an app fro their iPhone that does the same thing.

 

This was about the craziest angle I've been on... damn near crapped myself, and had weak legs after I got out of the mud hole I'd been going through. No pictures of the actual hole, just after the fact looking at the mud lines. If I'd had passengers I'm certain they would have gotten out... hell I wanted to get out.

 

It's funny you say that about passengers wanting out. My buddy (who has a completely stock 2011 4-door Sport S) actually opened the door and bailed out. He was spooked because he'd never been off-roading before.

I had it up on a huge gravel pile (passenger side). I was dragging the front pumpkin across it and was sliding sideways in my seat because of the angle. It was a blast.

I'll have to look for one of those tilt gauges. I think it'll come in handy.

I really appreciate all the replies. I have a lot of time on another Jeep forum (although I've only been on there since May... got my Jeep in June), but after lurking here for about a month, this one seems to be a great place and you guys are proving that to be the case.

 

It's funny you say that about passengers wanting out. ....

We took my wifes mother who has never been offroading up the canyon one weekend. On the poser rock she about pissed herself. I left the Jeep connected so it lifted the front tire. When the Jeep pitched onto both fronts and lifted the rear you would have thought her world was coming to an end.

I did it on purpose


Picture of the poser rock. I was on it from the opposite direction for the story.

 

Well you know I've installed one of those incline and roll indicator but never find the time to look at it when I'm in off-camber situations so can't tell you any values
To be honest I think it doesn't happen too often that one drives slowly into an extreme off-camber position where you tip over, most of the time it happens when you're still in what you've called the green area and suddenly go into a sideways slide where the momentum causes enough roll to tip you over.

 

On Red Wasp Canyon at Morris Mountain I was probably just over 40 degrees. I felt the jeep at the balance point and don't ever want to be in that again. Definitely a pucker factor moment. That same run we had a guy get in a bad tippy spot on the entry to Copperhead. We put a tow strap on his sliders and kept him down. You would be amazed how little it takes to tip the jeep one way or another. Just some weight on a tow strap can help a lot to keep you from rolling. Of course that only counts around the tipping point, not well past it. When that 5k pig decides to flop you are better off getting out of the path.

 

Trust me... he got an earful. I was *not* a happy camper.

 

I hate getting really off camber, it freaks me out every time.

 

x2.

 

This was at my tipping point when I had the XJ. They were literally rocking me for shits and giggles to freak me out. Dicks. I was pivoting on that back wheel.

 

A lot is going to depend on your rig. If you're running heavy 1-tons with a wider track, you can get a little more angle without going over. Suspension setup, sprung weight, etc. also make a difference.

Here's a pretty tippy pic I took when a group of us was in Johnson Valley during the Hammers back in Feb.

 

I've never measured an actual degree. I just try to use my best judgement and get a feeling of where my Jeep feels safe.

 

X3 on the off-camber. I try to keep my rig as level as possible but as well all know that can go south pretty quick. I never found the oops angle but I did find the perfect angle of balance in the photo.

 

I was in a narrow rut like that once. Turned the wrong way & felt it just gently go *tip* about 2" onto the dirt wall. I was hardly moving, so no damage. Got someone to stand on the step, backed up a bit & turned the other way.

Then getting up a step a little further along, it slipped sideways a bit & ripped off, and snapped, the drivers side OEM plastic step! :thankyou: Oh well. Good excuse to buy some steel slider steps!

Oh yes, if you have Aeroforce gauges, you can get a readout from the side G sensor on them. I have hit ~.5G cornering on road with no sign of tip, but that would only be about 30 degrees.

 

Old vid...but I'm sure some have not seen it. This will prove how easily you can roll when you are on the pivot point..

This is me last year on Outer Limits (Johnson Valley). My level gauge was bottomed out at 50* and I still felt "comfy" :th_pray:

No sway bars, tires at 7 PSI, and soft coils. Its all about seat time, and knowing how your rig reacts in every situation. OHH, and dont rush things, thats how you flop/roll. Never put yourself in a situation that you cant back out of.

* and this pic wasn't taken with the camera at an angle like some of the others

 

Those are some awesome pics.

I managed to get my general answer, but hell, keep the pics coming!

 

You want to see some "pants shittingly" extreme off-camber?!?

Check this out!

 

I have an iphone app called....wait for it..... "wheelin"

Never remember to use it when my ass is sucking up seat fabric though

 

we were on Pickle Gulch above Boulder this weekend, almost went over backward. Jeep says 53°, my guess is we were at 52.5°. I bought a gauge today. funny feeling to have that front end kind of floating. Then backing down it did it again. the GPS said something over 45° in that last 20 feet. We were in a bit of a hole on the pass/rear wheel it was a bit unnerving backing out of it. I probably should have had my wife hold down the front of the Jeep. iI don't think it would have taken much to get her out of the vehicle.
